between americans who say yes to the achievements of president obama and those backing romney is that fine, that delicate. recent polling shows the difference in popular backing for what obama has done, the saving of the auto industry, the rescue of the u.s. economy itself, the killing of bin laden, health care for working americans, against what romney is offering is roughly zero. as i said, it's that close. so tonight we look at how obama can regain the lead. is it with a populist message, a challenge to romney's politics, of, by, and for the wealthy? is it a step by step dismembering of romney's tax plan? or a tough, positive declaration of what he has managed to do by president? whatever strategy the president chooses, wherever he places the sharp focus of his message, his time, his energy, his money, it's time for the man in the white house to buy his ticket and take his chances. he's got three weeks to make it work. joining me is new york magazine's john heilemann who has a big article in this week's edition and former pennsylvania governor ed rendell. first, two new national polls.
